SU LKY LlSTER-PLOW.

SPECIFICATION forming part of Letters Patent No. 757,994, dated April19, 1904.

Application led April 9, 1903. Serial No. 151,831. (.No model.)

To all whom, it r11/(ty concern.-

Be it known that I, CALVIN R. DAvIs, a resident of South Bend, in thecounty of St. Joseph and State of Indiana, have invented certain new anduseful Improvements in SulkyLister plows andplanters; and it consists incertain novel features of construction and combinations and arrangementsof parts, as will be more fully hereinafter described, and pointed outin the claims.

In the accompanying drawings, Figure 1 is a view in side elevation,illustrating my improvements. Fig. 2 is a similar view of the oppositeside of the machine. Fig. 3 is a top plan view. Fig. 4 is a view intransverse section. Fig. 5 is a view in cross-section through the frame,illustrating the Vmounting of the roller 19. Fig. 8 is an enlarged viewof the driving-gear.

1 represents the frame of my improved lister, which comprises twolongitudinal bars bowed outward between their ends. and connected atintermediate points by arched cross-bars 2, three of which latter beingshown. The axle 3 is bowed between its ends and secured to the side barsof frame 1 by means of brackets 4 and U-bolts 5 and carries at each sideof its bowed portion sleeves 6, having lintegral sleeves 7 at rightangles thereto, in which the ends of a yoke 8 are securely bolted. Theintermediate portion of said yoke is mounted to rotate in brackets 9,secured to opposite sides of the beam 17 of my improved lister ordouble-moldboard plow 18. One of said sleeves 6 has an integral arm 10,to which one end of a counterbalance or lifting spring 11 is connected,the other or forward end of said spring being adjustably secured in abent bar 12, secured to one of the side bars of frame 1. This arm 1()has secured thereto an extension, which is pivotally connected by abifurcated rod 12L with one end of lifting-lever 111, fulcrnmedbetweenits ends on frame 1 and provided with a spring-pressed detent 15 to lockin any of the notches of a segment 16, secured to frame 1, and thus holdthe lever and lister in any position to which they may be moved. Theforward portion of plow-beam 17 when the lister is Vraisedout of theground engages `a roller 19, supported in a frame 20, secured ;to theunder face of the forward cross-bar 2,

and the rear portion of the beam engages the intermediate cross-bar 2,and its upward movement is limited thereby.

To the forward end of beam 17 a clevis is secured for the attachment oftwo draft-animals, and a cross-rod 21 is secured in bearings 22, boltedto the forward end of frame 1, and projects to one side beyond the same.When three draft-animals are employed, the pole-plate 23 is supported onrod 21 at one side of frame 1; but when four animals are used thepole-plate is secured on rod 22 between the side bars of frame 1, sothat the pole will extend between the two teams.

To the downwardly-bent end of beam 17, which forms a standard 25, alister 18 is secured by means of a suitable frog bolted to the standard.To the standard 25 a bracket 26 is securely bolted and provided with aslot for the reception of a bolt 27, which latter is also passed throughvertical elongated slots in the subsoiler-standard 28 and a wedgeshapedplate 29 recessed to receive the standard 28 and locate its wedgeportion between the forward edge of said standard and a lug 30 onbracket 26. It will thus be seen that the subsoiler can be adjustedvertically and set more or less on its point by adjusting thewedge-shaped plate 29 vertically.

An offset extension 31 is provided on bracket 26 and made with aninclined slot to receive a bolt 32, also passed through an elongatedvertical slot 33 in a web at the rear of seed-dropping tube 34 and holdthe latter directly behind thesubsoiler. The Lipper end of thisseed-tube 34 has a forwardlyeprojecting lug 35, pivoted to the upper endof the subsoilstandard 28 by a bolt. By so mounting the seed-tube itslower end can be adjusted back and forth, and as its connection withbracket 26 is through an inclined slot this pivotal adjustment of thetube varies its depth of planting. l/Vhen the tube is set in the forwardposition, the seed will drop to the bottom of the furrow; but when setfarther back, more or less, soil will fall to the bottom of the furrowin advance of the seed-tube, thus depositing the seed on pulverizedsoil. The amount of pulverized or loose soil on which the seed isdeposited may therefore be regulated by adjusting the seed-tube back andforth.

Covering-hoes 36 are provided and have a series of bolt-openings attheir upper ends for the reception of a bolt 37 to secure them to thelister-standard 25 and are spaced therefrom by washers 38. Theintermediate portions of said hoes 36 are also provided with a series ofbolt-holes for the reception of a bolt 39, passed through the bracket26, and vspacing-washers 40 arelocated on the bolt 39 between thebracket 26 and hoes. The covering-hoes may be set to a greater or lesserdepth by inserting the bolts into the different bolt-openings, so thatthe amount of soil required to cover the seed can be regulated to anicety. The lower ends of the hoes are formed into twisted blades andthe front edge made sharp for cutting. Said blades are twisted to theproper extent to concentrate the soil onto the seed. When the Washers 40are removed from bolt 39, the hoes are made to cut close up to theseed-bed, but may be set farther from the seed-bed by interposingwashers 40. Thus the Covering-hoes may be set to suit the differentconditions of the soil so as to cover the seed properly.

On the ends of axle 3 the main wheels 4l are mounted. The boxes of thesewheels are elongated on one side, as shown at 42, andl have sand-bandsintegral therewith. At times it becomes necessary to contract or widenthe traction ofthe lister, according to whether single or double listingis done and in order to have the traction-wheels follow the ridgesproperly as formed by the lister-base. In order to have the-adjustmentof the tractionwheels as simple as possible for the operator, I extendthe wheel-boxes to one side a distance of one-half of the necessaryadjustment, so that by reversing both traction-wheels 41 on the axle theproper gage is had. Thus when the wheels are in the 'position shown awide gage is had and when reversed with the 1 box or hub extensions42^outward a narrow gage is the result. One of these wheel hubs or boxesis made with internal notches at both ends, so that when in eitherposition it will clutch with lugs on the hub of driving-gear 43,supported to turn on the axle. On the axle 3,-adjacent to the gear 43, acasting 44 is mounted and made with an elongated pocket in which abearing-sleeve 45 is mounted and has lugs or trunnions 46 onoppositesides of one end supported in notches in the casting to givepivotal movement to the bearing in the pocket.. This bearing45 receivesthe forthereon and mounted to move longitudinally in an angular sleeve52, in which a spring 53 is mounted and presses against the head 5la toalways maintain the shaft extended longitudinally to proper workingposition, but permit it to contract to compensate for adjust-- ment ormovement of' theV lister. In. the upper end of sleeve 52 an angle-bar 55is secured by a bolt 54. This angle-bar 55 has a slot therein whichpermits of its adjustment onVV bolt 54 to regulate the tension of thespring.- The upper end of this angular sleeve 52 is connected by auniversal joint 56 with the seed-3' dropping shaft 57, supportedinsuitable bear-f ings on a bracket 58, secured to the upper end of thelister-standard. A seed-hopper 59 is secured on bracket 58, and itsdropper is oper` ated by a pinion 60 on shaft 57 meshing with a? toothedann ular rack on the drop per. By mak- .ing the clutch-teeth 50 inclinedon one side, as

shown, permits the pinion 48 to be turned in a reverse direction withoutoperating the seeddropper, and when the listerl is elevated to itshighest position the clutch member 5l will be drawn out of Contact withthe teeth 50 and permit the wheels and gear to turn without operatingthe seed-dropping mechanism, but will automaticall y clutch when thelister is lowered.

By inclosing the spring 53 in the angular sleeve 52 I protect the samefrom dirt and trash, which would interfere with the perfect operation ofthe machine. Communicating with the outlet of the said hopper is aconveyer-tube 6l, which is pivotally secured by a bolt 62 to the bracket58, and its lower ed rests in the upper wide endy of seed-tube 34, whichpermits adjustment of the latter without disturbing the feed, and anopening 63 is provided in the top of conveyer-tube 6l, so

thatthe operator can see at all times whether or not the seed areproperly dropping.

A tubular bracket 64 is secured by bolts to the converging rear ends ofthe side bars of frame l and is supported on the wheel-stand-4 ard 65.To the bottom end of said wheelstandard an adjustable wheel-axlebearingbracket 66 is secured by a bolt passed through a sleeve on thebracket and through the lower end of the standard 65 therein. Thisbracket is provided with notched or toothed elongated openings 67 toreceive bolts 68. passed through ears on the lower side of sand-bands69, in which axle-stubs are secured, and on said stubs the coveringwheels 7 O are mounted. Ears IOO IIO

are provided on the upper side of sand-bands 69 for the reception ofbolts 71 to pivotally support the axle-stubs and permit their angle tobe adjusted by adjusting-bolts 68 in the notched openings 67, andthereby adjust the angle of inclination of the coveringwheels 7 O.Suitable scrapers 7 2 are provided for these wheels 70 and are carriedby aT-shaped frame adjustably secured to bracket 66 by a bolt. Thetubular bracket 64 is mounted on standard 65, and the latter has acollar 7 3 secured thereon beneath bracket 64 by a setscrew 74 to limitthe downward movement of tubular bracket on the standard, and a seriesof notches are provided in the standard, in any one of which theset-screw may be projected to secure the collar 7 3 in any position andlevel the lister-frame in any depth of work.

On the upwardlyprotruding end of standard 65, above bracket 64, asegment 7 5 is secured by a set-screw 76 and locked against independentturning bya key on the segment fitting a keyway in the standard. Thissegment has a notch 77 in its periphery adapted toreceive a lug on oneend of an angular latch 78, pivoted between its ends on bracket 64, anda coiled spring 79 tends to force the latch into position with its lugin the notch 77 of segment 7 A rod 80 connects the end of this angularlatch 78 with a link 81, pivotally secured to lever 14, so that when thelister is raised out of the ground at the end of a furrow or in movingthe machine from place to place with the lister elevated the leveri14will hold latch 78 out of engagement with segment 7 5 and permit thecovering-wheels to freely caster; but when the lister is lowered forwork the spring 7 9 automatically forces the latch into lockedengagement with the segment to hold the covering-wheels true.

Suitable footrests 7 8 are secured to the frame 1 to permit the operatorto brace himself in operating lever 14 and controlling thedraft-animals.

The drivers or operators seat 82 is supported on a spring 83, secured tothe rear cross brace or bar 2 and in convenient reach of lever 14 tocontrol the raising and lowering of the lister.

A great many changes might be made in the general form and arrangementof the parts described without departing from my invention, and hence Ido not confine myself to the precise details set forth, but considermyself at liberty to make such slight changes and alterations as fairlyfall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In a sulky-lister, the combination of a frame comprising longitudinalbars, cross-bars connecting the same, a lister movably connected withthe frame and whose upward movement is limited by one of the cross-bars,and a roller on another bar against which the beam of the lister engageswhen elevated.

2. In a sulky-lister, the combination with a frame, an axle securedthereto, and wheels on the axle, of a lister, a yoke connected betweenits ends to the beam of the lister, sleeves on the axle to which theends of the yoke are secured, and a lever to turn one of said sleevesand raise and lower the lister.

3. In a sulky-lister, the combination with a frame comprisinglongitudinal bars connected by cross-bars, of an axle bowed between itsends and secured to the longitudinal bars of the frame, wheels on saidaxle, a lister, a yoke pivotally secured between its ends in brackets onthe lister-beam, sleeves on the axle to which the ends of the yoke aresecured, an arm on one sleeve, and a lever fulcrumed between its endsand connected at one end by a link with said arm.

4. In a sulky-lister, the combination with a frame, an axle securedthereto and wheels on the axle, of a lister, sleeves on the axle,integral collars thereon at right angles thereto, a yoke pivotallysecured between its ends to brackets secured to the lister-beam, andhaving its ends secured in said collars, an arm on one sleeve, alifting-spring connecting said arm with the frame and adjustablymounted, and a lifting-lever also connected with said arm.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
